What we repair, in one sentence
Pro Truck Services repairs and maintains commercial diesel trucks and trailers — Class 8 tractors, box and straight trucks, medium-duty Class 5–7, and the trailers they pull — at 3036 Orange Grove Ave in North Highlands on the I-80/Watt Avenue corridor, at your yard or dock by scheduled mobile visit, and at roadside when a truck is already stopped. Every job is diagnosed before anything is replaced, and you approve the estimate before work starts. Not a pickup or passenger-car shop.
How the catalog below is organized
Services are grouped by the system that failed, because that is how trucks break: engine and powertrain, emissions and aftertreatment, brakes and chassis, trailers, electrical and cab, inspections, maintenance and fleet programs, and mobile and emergency response. Two more groups sort the same work by what you drive — truck manufacturer and engine platform — because on a modern truck the engine decides the repair path more than the badge does. If you only know what the truck is doing, the truck problems index works backwards from the symptom to the right service; the guides explain the rules and the cost decisions behind the bigger jobs.
Where the work happens
Shop work runs Monday to Friday, 8 to 5, with scheduled overnight and weekend work available by arrangement for fleets that cannot spare trucks in the day. Internal engine, transmission and anything needing a lift or press stays in our bays; brakes, electrical, air leaks, lights, PM services and most trailer work travel well to your yard. When a truck cannot move, towing can be arranged. Call (916) 571-8888. Мы говорим на Русском.
Common questions
Do you work on diesel pickups or RVs?
No — the bays, parts and diagnostics here are set up for commercial trucks and trailers. A light-duty diesel specialist will serve a personal pickup better, and we will say so on the phone.
Which page should I start from if I only have a warning light?
The truck problems index. Each symptom page says whether it is safe to keep driving, what usually causes it, and which service fixes it — derate, DPF light, DEF countdown, air loss, won’t start, overheating and more.
Can all of these services be done at my yard?
Most of the everyday ones — brakes, electrical, air systems, lights, PM, tires and trailer hardware. Internal engine and transmission work, and anything that needs a lift, is done in the North Highlands shop, and we will tell you which is which before the visit is booked.
Do you repair trailers as well as tractors?
Yes — brakes, air, lights and wiring, doors, floors, landing gear, suspension and alignment on dry vans, flatbeds and reefer trailers. The refrigeration unit itself is a separate trade; we will say plainly when a reefer needs that specialist.
